Diffusive wave approximation to the shallow water equations: Computational approach
MetadataShow full item record
We discuss the use of time adaptivity applied to the one dimensional diffusive wave approximation to the shallow water equations. A simple and computationally economical error estimator is discussed which enables time-step size adaptivity. This robust adaptive time discretization corrects the initial time step size to achieve a user specified bound on the discretization error and allows time step size variations of several orders of magnitude. In particular, in the one dimensional results presented in this work feature a change of four orders of magnitudes for the time step over the entire simulation. © 2011 Published by Elsevier Ltd.

Evaluating the effectiveness of organisational-level strategies with or without an activity tracker to reduce office workers' sitting time: A cluster-randomised trialBrakenridge, C.; Fjeldsoe, B.; Young, D.; Winkler, E.; Dunstan, D.; Straker, Leon; Healy, G. (2016)© 2016 The Author(s). Background: Office workers engage in high levels of sitting time. Effective, context-specific, and scalable strategies are needed to support widespread sitting reduction. This study aimed to evaluate ...
